We profile five players who have turned out for both West Ham United and Sunday's hosts Burnley...
1. Herman Conway
Born in Lincolnshire in October 1908, goalkeeper Herman Conway was one of a number of Hammers to begin his career with Midland League club Gainsborough Trinity.
Among the other West Ham United players to turn out for Trinity were George Gresham, Joe Cockroft, Stan Foxall Freddie Fenton and William Ingham.
Conway became Gainsborough’s regular first-team stopper in March 1929 before joining Burnley a year later.
After four years and 81 Football League appearances in the top two divisions, Conway joined West Ham in 1934, making his debut against his former club at the Boleyn Ground on 27 August.
The stopper totalled 127 Second Division and FA Cup appearances over five seasons prior to the outbreak of World War Two.
2. Jack Tresadern
Leytonstone-born left-back Jack Tresadern began his career with non-league Wanstead and Barking Town before joining the Hammers in July 1913.
West Ham United were then a Southern League side, but the defender remained with the Club throughout the World War One and started the Hammers’ third Football League fixture at Lincoln City on 6 September 1919.
Tresadern was a first-team regular for the next four seasons, totalling 130 Second Division appearances.
In 1922/23, he helped West Ham to win promotion and appeared in the FA Cup final defeat by Bolton Wanderers at Wembley.
The full-back joined Burnley in October 1924 and played 22 league games for the Clarets in the First Division before ending his career with Northampton Town.
3. Matt Taylor
Still going strong with League Two club Northampton Town at the age of 35, Oxford-born Matt Taylor has enjoyed a successful career at the highest level.
After coming through the ranks at Luton Town, Taylor helped Portsmouth win promotion to the Premier League for the first time in 2003.
There, his expert left-foot delivery and penchant for scoring spectacular goals made him a favourite, and he continued to impress during four seasons with Bolton Wanderers.
Taylor joined West Ham United following relegation in 2011 and set up Carlton Cole’s opening goal in the Championship Play-Off final in May 2012.
After three seasons and 90 appearances, he moved to newly-promoted Burnley in 2014, but suffered relegation a year later.
He joined Northampton in summer 2016 and made 48 appearances this season, scoring eight goals.
4. Reg Attwell
Born in Shropshire, Reg Attwell joined West Ham United from non-league Denaby United during the 1937/38 season.
The wing half made his debut at Sheffield United in April 1938, but did not play again before the Second World War, during which he served in the Army.
After guesting for Leeds United and Burnley, he returned to the Hammers and played four more Second Division games in autumn 1946 before joining the Clarets on a permanent basis.
After winning promotion in his first season at Turf Moor, Attwell helped Burnley settle into life in the First Division over the next eight seasons.
After scoring eleven goals in 269 matches, he moved to Bradford City for the 1954/55 season before retiring at the age of 35.
Attwell passed away in Burnley at the age of 66 in December 1986.
5. Zavon Hines
An Academy of Football graduate, Zavon Hines was loaned to Coventry City in 2008, where he made his senior debut under Chris Coleman in March of that year.
On returning to West Ham United, Jamaica-born Hines scored on his debut in a League Cup win over Macclesfield Town in August 2008.
Fifteen months later, his headline moment arrived in the shape of a last-minute Premier League winner against Aston Villa at the Boleyn Ground.
However, injury issues led him to depart east London in 2011, having made 31 appearances and scored three goals.
Hines joined Burnley in August 2011 and played 13 times in the Championship before embarking on a career that has seen him turn out for AFC Bournemouth, Bradford City, Dagenham & Redbridge and current club Southend United.
